As the cool autumn air settles in over Ohio, residents of Columbus, Cincinnati, Wilmington, and surrounding regions can expect a significant shift in weather conditions. According to the National Weather Service (NWS), a low-pressure system made its grand entrance on Sunday, generously sprinkling much-needed rain across the area, accompanied by notably breezy conditions. National Weather Service forecast reports a day filled with robust rain showers, thanks partly to the pressure interaction between a high off the Atlantic Coast and a low-level jet (LLJ).
